The Google Code page is actually not empty [1]. The rest will be more
populated once more testing has been done.
I've chosen to provide the overlay / source / binaries as a tarball
for now until a few more people have tested it out. Actually, this is
a good reminder to put together a small qemu image so that people
could easily try out. I've been putting that off since work has been
fairly busy lately. Also, I really need to upload the arm toolchain I
built too.
Note to self...

Yes, please see the link at [1].
